DESCRIPTION

1. Technical Field

The present invention relates to a pharmaceutical preparation comprising a compound having a tropone structure and in particular to remedies/preventives (therapeutic or preventive agents) against frequent urination (pollakiuria) or urinary incontinence.

2. Background Art

With the aging society, pollakiuria, urinary incontinence, and dementia become a social problem. There is a need for medical care with the aim of maintaining QOL (quality of life) in one's old age. In particular, pollakiuria and urinary incontinence limit the range of behavior for the aged and significantly lower their quality of life, thus bringing about a very heavy burden not only on a patient but also on a nurse or a care worker.

Tropone compounds including hinokitiol are marketed as a part of daily articles as a bathing agent and a humectant. Further, they are extensively studied as pharmaceutical preparations. For example, JP-A 6-509318 discloses such compounds as therapeutic and preventive agents against ischemic diseases such as cerebral vascular diseases and heart vascular diseases. However, the effect of the compounds having a tropone structure on pollakiuria and urinary incontinence is not known.

As chemicals for treatment of diseases such as pollakiuria and urinary incontinance, an anticholinergic agent, a smooth muscle direct relaxant, a, tricyclic antidepressant, etc. have been used, but the action of the smooth muscle direct relaxant on the bladder is lower as that of the anticholinergic agent, and the effect thereof on urinary incontinence is unsatisfactory. Further, the anticholinergic agent has the side effects of dry mouth, ischuria, etc. In the change of the human bladder smooth muscle along with aging, an increase in atropine resistance contraction is observed, and these chemicals are not necessarily adequate in respect of the effect and side effects. In particular, the chemicals alone having an anticholinergic action are considered unsatisfactory in their effect on urinary incontinence for the aged. In the clinical field of chemotherapy at present under these circumstances, development of a new therapeutic agent for pollakiuria and urinary incontinence is desired earnestly. Further, with the highly aging society near at hand, comprehensive therapy came to be conducted for nerve diseases such as cerebral apoplexy, spinal damage or nerve-degenerated disease, and further collective therapy for uterine cancer and rectal cancer and therapy for diabetes have been developed thereby enabling the prolonging of the life of a fatal patient in the past, and as a result and also for raising the QOL of the patient, there is an increasing need for treatment and prevention of pollakiuria and urinary incontinence.

DISCLOSURE OF THE INVENTION

As a result of eager study to solve the problem described above, the present inventors unexpectedly found that compounds having a tropone structure have the following effects: (1) they increase the bladder capacity by their inhibitory action on urination reflexes, thus prolonging urination intervals, (2) they do not cause dry mouth and ischuria as the side effects of the anticholinergic agent, and (3) they are also effective for patients observed to have an increase in atropine resistance contraction and the like, and the present inventors found that these compounds are effective as a therapeutic and preventive agent against pollakiuria and urinary incontinence, and the present invention was thereby completed.

Test

Micturition reflex inhibitory effects of the compounds having the tropon structure according to the present invention was demonstrated by the effects on the rhythmic bladder contraction using the modification of the Kaseda's method (RINSHO SEIRI 5, 540-547(1975)).

Method

The Effects on the Rhythmic Bladder Contraction Effect in Rat:

A male Wistar male rat anesthetized with intraperitoneal administration of urethane (1 g/Kg) was subjected to amidoline abdominal incision to expose the bladder, whose dome was cut to make a small opening for inserting a polyethylene tube catheter before ligation. The other end of the catheter was connected to a pressure transducer to measure intravesical pressure. The rat was left for a small period with the urethra ligated. Warmed physiological saline was injected into the bladder through a catheter inserted in the bladder side of an ureter to induce rhythmic bladder contraction. Then change in the intravesical pressure was depicted on a recorder through the pressure transducer. A drug was administered in the common cervical vein by 5 mg/Kg. The drug effect was expressed as prolongation coefficient in rhythmic bladder contraction.

Prolongation Coefficient=[maximum contraction interval after administration]/[mean contraction interval for 10 min before administration].
